About Kennady Diamonds
The Kennady North project comprises thirteen leases and claims located to the west and north of the four leases controlled by the Gahcho Kué Joint Venture between De Beers Canada Inc. (51%) and Mountain Province (49%).

Exploration at Kennady North commenced in the late 1990's and resulted in the discovery of the diamondiferous Kelvin, Faraday and Hobbes kimberlites. The number of diamonds recovered from these kimberlites and the size-frequency distribution indicate that they may be of comparable grade to the 5034 (1.77 carats per tonne) and Hearne (2.10 carats per tonne) kimberlites at the Gahcho Kué JV. Exploration samples from Kelvin and Faraday returned a relatively large number of macro diamonds with the two largest being a 0.4 carat diamond from Faraday and a 0.09 carat diamond from Kelvin.

The known kimberlites at Kennady North do not explain all the kimberlitic indicators previously recovered from glacial till sampling. Exploration at Kennady North was suspended in 2004 when Mountain Province focused the Company's attention on the Gahcho Kué pre-feasibility and feasibility studies.

Exploration at Kennady North recommenced during 2011 with a 50-meter line-spacing airborne gravity gradiometry (AGG) survey over the entire 123.6 square kilometer project area. The survey identified 106 geophysical targets.  The Company has also completed a 560-line-kilometre total magnetic field (MAG) ground survey over the 106 geophysical targets identified by the AGG survey. The high priority targets identified through the AGG and MAG surveys will be scheduled for drilling as soon as a land use permit is obtained.

About Mountain Province Diamonds
Mountain Province is a 49% participant with De Beers Canada in the Gahcho Kué JV located at Kennady Lake in Canada's Northwest Territories. The Gahcho Kué Project consists of a cluster of four diamondiferous kimberlites, three of which have a probable mineral reserve of 31.3 million tonnes grading 1.57 carats per tonne for total diamond content of 49 million carats.

Gahcho Kué is the world's largest and highest grade new diamond development project. A December 2010 feasibility study filed by Mountain Province (available on SEDAR) indicates that the Gahcho Kué project has an IRR of 33.9%.

The Gahcho Kué project is currently the subject of an environmental review, which is expected to be completed in late 2012. Subject to successful permitting, development of the first mine at Gahcho Kué is expected to commence in 2013.
